The effect of music intervention on sedation in elderly patients undergoing transurethral resection of prostate under spinal anesthesia: a prospective randomized controlled clinical trial.

PURPOSE: Music intervention is commonly used as a non-pharmacologic therapeutic modality to alleviate anxiety in perioperative patients. This study aimed to assess the sedative and anxiolytic effects of music on elderly patients receiving transurethral resection of prostate (TURP) under spinal anesthesia.

METHODS

This was a prospective randomized controlled trial on patients who aged over 60 and received TURP under spinal anesthesia. Participants were randomized to the music group or the control group (no music). The primary outcome was perioperative BIS values, and the secondary outcomes were patient's perioperative anxiety levels, heart rate (HR), blood pressure, and patient satisfaction score.

RESULTS

A total of 82 patients were analyzed. The perioperative BIS values in the music group were significantly lower than those of the control group at almost all time points (P < 0.001), as well as showed a significant reduction compared with baseline (P < 0.001), whereas the control group did not. In comparison with the control group, systolic blood pressure (SBP) significantly decreased in the music group at the beginning (mean difference, - 8.0 mmHg; 95% CI - 15.70 to 0.35; P = 0.041) and the 60th minute (mean difference, - 7.9 mmHg; 95% CI - 15.30 to 0.51; P = 0.037) of TURP. Furthermore, compared with baseline within the music group, diastolic blood pressure (DBP) and HR significant reduced at whole time points (P < 0.05), yet the control group not.

CONCLUSION

Music intervention effectively provided slight sedation for elderly patients when undergoing TURP under spinal anesthesia without sedatives.
